Answer:

A] Probability = 1/n ; B] Number = 8

Step-by-step explanation:

Total counters = n , Blue counter = 1 , Red counters (remaining) = n -1

A] Prob (One blue, & One red counter) = (Blue counter / Total counters) x (Red counters / Total remaining counters) = [1 / n] x [ (n -1) / (n-1)] = 1 / n

Alternative, Prob  (One red, & one blue) = (Red counter / Total counters) x (Blue counters / remaining counters) = [ (n-1) / n ] x [1 / (n-1) ]  = 1 / n

B] Prob (each color , a blue & red counter taken) = 0.125  {Given}

By A], this Prob = 1/n.

So, 0.125 = 1/n → n = 1 / 0.125 = 8

Answer: 6

Step-by-step explanation:

ab:pq = 5:35, and ac:pr=x:42

because ab:pq=5:35, then it becomes 1:7, as you can divide by 5 on both sides. Ac:pr=x:42, and 42=7x. When you solve that x=6.

hope that makes sense!

Answer: [tex]9\pi \ in.^2[/tex]

Step-by-step explanation:

Given

The height of the cylinder is [tex]h=7\ in.[/tex]

The volume of the cylinder is [tex]V=63\pi \ in.^3[/tex]

The volume of the cylinder is the product of area and height

[tex]\Rightarrow V=\pi r^2h\\[/tex]

Insert the values

[tex]\Rightarrow 63\pi =A\times 7\\\\\Rightarrow A=\dfrac{63\pi}{7}\\\\\Rightarrow A=9\pi\ in.^2[/tex]

Thus, the area of the cross-section is [tex]9\pi \ in.^2[/tex]

Answer:

The correct graph should have an x-intercept of 24, a y-intercept of 72, connected by a dashed line, with shading to the right

Step-by-step explanation:

y > -3x + 7

The correct graph should have an x-intercept of 7/3, a y-intercept of 7, connected by a dashed line, with shading to the right

Answer:

4/5

Step-by-step explanation:

If we are given this value as a percent we can simply turn that percentage into a fraction. 80% would be 8/10 but since the question wants the fraction in simplest form we can achieve this by dividing both the numerator and denominator by 2. This would give us 4/5, which if we divide the numerator by the denominator we get 0.80 which is 80%. Therefore, the fraction of those surveyed  that had at least one brother or sister is 4/5

Answer:

To graph the equation, you need to find the slope and y-intercept.

y = mx + b

⬑[slope-intercept formula; m is the slope, and b is the y-intercept]

y = 4x + −1

⬑[given equation before being simplified]

y = 4x − 1

⬑[given equation]

║m = 4

║b = (0, −1)

Proof:

m = [tex]\frac{rise}{run}[/tex] = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

x₁ = 0

x₂ = 1

y₁ = −1

y₂ = 3

m = [tex]\frac{3 - -1}{1 - 0}[/tex]

║m = 4

║b = (0, −1)

[the value for x₁ and y₁ equals the y-intercept: (0, −1)]

Step-by-step explanation:

Answer: f(x)

Step-by-step explanation:

The function g(x) has the greater maximum value. So, option (A) is the correct answer.

"The graph of a function f is the set of all points in the plane of the form (x, f(x)). We could also define the graph of f to be the graph of the equation y = f(x). So, the graph of a function if a special case of the graph of an equation".

For the given situation,

The function f(x) is expressed as -3x^2 + 6x +4

The function g(x) is shown in the graph.

Plot the function f(x) in the graph to compare with g(x).

The graph for f(x) is shown below.

The function f(x) is the decreasing function, so it has only a minimal value.

The function g(x) is the increasing function, so it has a maximum value.

Hence we can conclude that the function g(x) has the greater maximum value. So, option (A) is the correct answer.
